Homework Statement
Walt and Wolfie collide in bumper cars of mass 50 kg each. Walt has a mass of 78 kg, and Wolfie has a mass of 61 kg. Walt strikes Wolfie from the rear at V = 3.7 m/s. If the collision is elastic, Wolfie is initially at rest, and Walt's final speed is 0.2655 m/s in the same direction, what is Wolfie's speed after the collision?
Homework Equations
1/2mv^2=1/2m(vprime^2+vprime^2)
The Attempt at a Solution
I don't really know where to begin at... I don't think the equation above is the one I need but, I can't find any others. I know I don't use S=d/t. I also looked at the hyperphysics site but, the only equations for collisions and information on collisions that I could find were for head to head... Can anyone give me a push in the right direction? (no pun intended :p)
